Yeah I know... they have a free version too.
This is a slightly higher tech cartoon version of Craigslist. Yup 99% of the people that use it suck badly at whatever aspect of music they aspire to.
FACT... if you are truly good at playing your instrument and/or singing, and have been at it for a long time, you've already established a dependable network of like-minded peers over the years. People you've played with professionally, or even on an amateur/avocation level. AND... you don't need these crappy internet affinity group subscriber services.
All of us that have been at it successfully in the music world for a while surely already know this.
Gone are the days when people were a bit more honest and objective about their skill level and experience. But these days with YT, FB (and all the rest of the garbage social media), and smartphone, any untalented idiot can put up garbage, or tweak content technically to make it appear as something it's not.
Gone are the days when people made skill and experience judgments quickly and person. Now they'd just rather mentally masturbate behind a PC with protools and doctor content. "GOT A VIDEO CLIP?" Sound familiar?
Bandmix is just another scamming bunch of grifters hiding behind a PC and current technology.
